ProCharger unleashes the world's most powerful centrifugal supercharger. The new ProCharger F-4 pushes 5,400 CFM at 50+ psi. On a 521 cid BAE HEMI engine and methanol fuel, the F-4 has produced 3,384 HP at 7800 RPM on that engine.

In early December, word started trickling out within the racing community about the recently conducted F-4 engine dyno sessions. But now, with the official press release and video from ProCharger, the 3,384 HP dyno pull is literally taking the Internet and PRI attendees by storm. Within 48 hours of the video being posted on Youtube.com, it had already received more than 10,000 views and is being talked about numerous racing and high-horsepower forums and web sites.

ProCharger is using the 2010 PRI show to debut the production version of the updated F-4 supercharger. Designed specifically for ultra-high horsepower applications, the F-4 has spent nearly a year undergoing design verification and testing, including advanced aerodynamic and rotordynamic testing at ProCharger, and some jaw-dropping, on-engine dyno testing with some very knowledgeable racers and tuners.

“The new F-4 takes centrifugal supercharging to an entirely new level - 3,200 plus horsepower, or in the case of this most recent engine dyno testing, just under 3,400 horsepower,” notes Dave Werremeyer, Motorsports Operations Coordinator at ProCharger. "We are looking forward to working with some of the top engine builders and racers in the industry to see the F-4’s true performance potential realized on the track and in other motorsports applications."

Werremeyer notes that the current ProCharger F-3 superchargers have proven capable of 2,000 horsepower on pump gas and nearly 3,000 horsepower on engines specifically designed for use with a supercharger and running alcohol fuels. However, as an industry innovator, the engineering staff and R&D team at ProCharger recognized the desire of racers and engine builders for an even larger centrifugal supercharger design.

"This updated F-4 is the next step in providing today's racers with the centrifugal supercharger solution they need to produce 3,200 to 3,500 horsepower," says Ken Jones, CEO at ProCharger. "Building on the proven power and durability of the legendary F-3 family of superchargers, the F-4 provides some distinct and quantifiable aerodynamic and compressor performance advantages."
